Iga Results

Hi everyone

I've posted on here before with all of my symptoms. I had a blood test for celiac last month which came back negative. I went to the dogs today to get my iron tested and while I was there I asked what exact tests I had for celiac. She said I only had one which was iga and the result was 0.8. What is the normal range?

Thanks

Serologic panel

Of the commercially available serologic tests that aid in the diagnosis of celiac disease, no one test is ideal. Using multiple serologies increases the diagnostic yield. Therefore, in the United States, screening in patients with possible celiac disease should consist of a panel of the following serologic tests:

Anti-gliadin antibodies (AGA) both IgA and IgG

Anti-endomysial antibodies (EMA) - IgA

Anti-tissue transglutaminase antibodies (tTG) - IgA

Total IgA level.

The reason for the use of the panel to detect celiac disease is several fold. They include selective IgA deficiency (SIgA deficiency), lack of concordance of endomysial antibody and tTG, and the occurrence of seronegative celiac disease.

You need to be tested with the full panel.

Thanks for replying. Those links you guys have sent are interesting.

I think it was the IGA (EMA) one the doc did. She also tested me for wheat allergy and several other allergies which came back negative. If someone had celiac would their wheat allergy test come back positive??

I have looked on the internet and I must be stupid but I can't find anything which tells me what the normal range is for IGA, just so I can see where I sit.

Thanks

Normal, or ranges can vary from lab to lab. Each lab has their range of distinction.

Celiac and a wheat allergy are two completely different things. Celiac is an autoimmune disease, an allergy is still an immune response, but it's not autoimmune and the tests are based on two different component of the immune system. An allergy test is IgE based, and celiac testing is IgA/IgG based.

That being said, you can have one or both, but just because you have celiac doesn't mean you have an allergy, and just because you have an allergy doesn't mean you have celiac.

Ask the doctor for your test results so you can actually see what the result was compared to the range, and have her run a complete celiac panel.

Well I am actually waiting on a hospital appointment for a biopsy so do you think I should wait and see how that goes or do you think I should still get a blood test for full celiac panel?

      Celiac and allergic to common subs and adds in prepared foods

      By DAR girl · Posted

      Looking for help sourcing gluten-free products that do not contain potato or corn derived ingredients. I have other autoimmune conditions (Psoriatic Arthritis and Sjogrens) so I’m looking for prepared foods as I have fatigue and cannot devote a lot of time to baking my own treats.

      Disregarded

      By Scott Adams · Posted

      I am so sorry you're going through this. It's completely understandable to feel frustrated, stressed, and disregarded after such a long and difficult health journey. It's exhausting to constantly advocate for yourself, especially when you're dealing with so many symptoms and positive diagnoses like SIBO, while still feeling unwell. The fact that you have been diligently following the diet without relief is a clear sign that something else is going on, and your doctors should be investigating other causes or complications, not dismissing your very real suffering.

      Paying for my own Celiac screening at WalkInLab so a positive result doesn’t become part of my medical history

      By Oldturdle · Posted

      It is just so sad that health care in the United States has come to this.  Health insurance should be available to everyone, not just the healthy or the rich.  My heart goes out to you.  I would not hesitate to have the test and pay for it myself.  My big concern would be how you could keep the results truly private.  I am sure that ultimately, you could not.  A.I. is getting more and more pervasive, and all data is available somewhere.  I don't know if you could give a fake name, or pay for your test with cash.  I certainly would not disclose any positive results on a private insurance application.  As I understand it, for an official diagnosis, an MD needs to review your labs and make the call.  If you end up in the ER, or some other situation, just request a gluten free diet, and say it is because you feel better when you don't eat gluten.      Hang in there, though.  Medicare is not that far away for you, and it will remove a lot of stress from your health care concerns.  You will even be able to "come out of the closet" about being Celiac!

      Yes, I've posted a few times about two companies: Request a Test and Ulta Labs. Also, pretty much we can all request any test we want (with the possible exception of the N protein Covid test and I'm sure a couple of others) with Lab Corp (or Pixel by Lab Corp) and Quest. I much prefer Lab Corp for their professionalism, ease of service and having it together administratively, at least in DC. And just so you know, Request a Test uses Lab Corp and Quest anyway, while Ulta Labs uses only Quest. Ulta Labs is cheaper than Request a Test, but I am tired of dealing with Quest, so I don't use them so much.

      Does Dailymed.nlm.nih.gov site have filters for gluten?

      By Scott Adams · Posted

      PS - I think you meant this site, but I don't believe it has been updated in years: http://glutenfreedrugs.com/ so it is best to use: You can search this site for prescriptions medications, but will need to know the manufacturer/maker if there is more than one, especially if you use a generic version of the medication: To see the ingredients you will need to click on the correct version of the medication and maker in the results, then scroll down to "Ingredients and Appearance" and click it, and then look at "Inactive Ingredients," as any gluten ingredients would likely appear there, rather than in the Active Ingredients area. https://dailymed.nlm.nih.gov/dailymed/
